Support for thumbnails on SLDDRW, SLDPRT, SLDASM file formats

[John Pye <john pye anu edu au>]

Hi all

I came across some interesting information about files from the
(commercial closed-source) program SolidWorks. This program uses the
Microsoft 'structured file' storage format, and contains preview bitmaps
that could very usefully be displayed using for Linux users via
Nautilus. This would be especially good because SolidWorks doesn't
provide a Linux-based file viewer of any sort (shame on them!).

On Ubuntu 7.10, with the package libgsf-bin installed, I was able to
extract a PNG preview from various files using this command:

gsf cat mydrawingfile.SLDDRW PreviewPNG > preview.png && eog preview.png

What would be required to make Nautilus display those preview images
automatically?

Cheers
